The purpose of this study is to evaluate the safety and efficacy of a novel topical treatment for dry scalp conditions, including dandruff, seborrheic dermatitis, and atopic dermatitis. The study investigates clinical improvements in symptom severity, participant experience with the treatment, and changes in the scalp microbiome before and after use. By studying this treatment, the investigators aim to provide children and adults with a natural, effective option for managing dry scalp conditions.
This study evaluates the safety and efficacy of a novel topical scalp treatment for dry scalp conditions, including dandruff, seborrheic dermatitis, and atopic dermatitis. The treatment contains Lactobacillus sp., honey, and turmeric in an emollient base, hypothesized to alleviate symptoms by addressing microbial imbalances, reducing inflammation, and promoting scalp hydration. The study will enroll 15-40 pediatric participants aged 1-17 years and 20-40 adults aged 18 and older, all clinically diagnosed with dry scalp. All participants will apply the treatment over a 14-day period. Adults will use the treatment daily, while pediatric participants will apply it 2-3 times weekly. Other scalp therapies will be discontinued during the study period. The study aims to explore the treatment's potential to improve clinical severity, enhance quality of life, and positively impact the scalp microbiome, providing a natural, effective option for managing dry scalp conditions.

Efficacy Determined Using the Investigator's Global Assessment (IGA) - Adult
The Investigator's Global Assessment (IGA) is a 5-point scale used to evaluate the severity of dry scalp conditions. Scores range from 0 (clear) to 4 (severe disease), based on clinical signs such as flaking, erythema, and pruritus. Assessments were conducted at baseline and endpoint to evaluate the efficacy of the treatment in reducing symptom severity.
Time frame: Baseline, 2 weeks (Study Endpoint)
Efficacy Determined Using the Investigator's Global Assessment (IGA) - Child
The Investigator's Global Assessment (IGA) is a 5-point scale used to evaluate the severity of dry scalp conditions. Scores range from 0 (clear) to 4 (severe disease), based on clinical signs such as flaking, erythema, and pruritus. Assessments were conducted at baseline and endpoint to evaluate the efficacy of the treatment in reducing symptom severity.
Time frame: Baseline, 2 weeks (Study Endpoint)
Efficacy Determined Using the Total Severity Scale (TSS) - Adult
The Total Severity Scale (TSS) evaluates the severity of dry scalp conditions by averaging individual scores for erythema, scaling, and pruritus of scalp lesions. Each component is scored on a 4-point scale, ranging from 0 (none) to 3 (severe). The TSS is calculated by summing the scores of individual subscales, each representing a key symptom or feature of the condition, for a total possible score range of 0 to 9, with higher scores indicating greater severity. TSS assessments were conducted at baseline and 2 weeks (Study Endpoint) to determine the treatment's efficacy in reducing symptom severity.

Change in Bacterial Composition of Scalp Using RODAC
This exploratory outcome assesses whether the topical treatment alters the scalp microbiome to more closely resemble that of a healthy scalp. Scalp samples were collected at baseline and endpoint using swabs and analyzed with 16S ribosomal RNA (rRNA) sequencing for bacterial diversity and internal transcribed spacer (ITS) sequencing for fungal diversity. Colony counts were measured using the Replicate Organism Detection and Counting (RODAC) method to evaluate bacterial and fungal load changes.
Time frame: 6 months
Quality of Life Change - Adult
Quality of life was assessed using the ScalpDex-23, a validated 23-item instrument designed to evaluate the impact of scalp dermatitis on symptoms, functioning, and emotions. Each item is scored on a 5-point Likert-type scale ('Never' = 0, 'Rarely' = 25, 'Sometimes' = 50, 'Often' = 75, 'All the time' = 100), with higher scores indicating greater impairment. Subscale scores were calculated for Symptoms (7 items), Emotion (8 items), and Functioning (8 items) by averaging the respective item scores. The total ScalpDex-23 score was calculated as the average of the three subscale scores, yielding a final value ranging from 0 to 100. Assessments were conducted at Baseline and after 2 weeks (Study Endpoint) to measure changes over time.

Quality of Life Change - Child
Quality of life was assessed using the ScalpDex-23, a validated 23-item instrument designed to evaluate the impact of scalp dermatitis on symptoms, functioning, and emotions. Each item is scored on a 5-point Likert-type scale ('Never' = 0, 'Rarely' = 25, 'Sometimes' = 50, 'Often' = 75, 'All the time' = 100), with higher scores indicating greater impairment. Subscale scores were calculated for Symptoms (7 items), Emotion (8 items), and Functioning (8 items) by averaging the respective item scores. The total ScalpDex-23 score was calculated as the average of the three subscale scores, yielding a final value ranging from 0 to 100. Originally, assessments were to be conducted at baseline and endpoint to measure changes in quality of life. However, for children, only midpoint data were collected, so change could not be measured.
